Phosphine, bis(1,1-dimethylethyl)(2,2-dimethylpropyl)- - Introduction
Di-t-butylneopentylphosphine(Di-t-butylneopentylphosphine) is an organophosphorus compound with the chemical formula C14H31P. It is a colorless liquid with a pungent odor. The following is a description of the nature, use, preparation and safety information of the Di-t-butylneopentylphosphine:
Nature:
Di-t-butylneopentylphosphine is a colorless liquid at room temperature, soluble in some organic solvents such as ether and dichloromethane. It is easily oxidized in air, so it should be stored under inert gas. It is a strong reducing agent that reacts with oxygen, halogens or other oxidants.
Use:
Di-t-butylneopentylphosphine is widely used in organic synthesis. It can be used as a ligand to form complexes with transition metals for catalytic reactions. It can also be used for reduction reactions, coupling reactions and the synthesis of compounds such as glyphosate.
Preparation Method:
Di-t-butylneopentylphosphine are usually prepared by means of acid catalysis. First, di-tert-butylchlorophosphine is reacted with neopentyl lithium to form a Di-t-butylneopentylphosphine lithium salt. Then, it is reacted with an acid to produce the target product Di-t-butylneopentylphosphine.
Safety Information:
Use Di-t-butylneopentylphosphine should pay attention to its toxicity and irritation. Avoid contact with skin and eyes, and make sure to operate in a well-ventilated area. Personal protective equipment such as gloves and glasses should be worn during use. In addition, correct operating methods should be followed, and chemicals should be stored and handled properly to ensure safety. If an accident occurs, immediately take appropriate first aid measures and seek medical help.
